Iothic and Carahsoft Make CORE (d)OISP Available Through Public Sector Contracts

April 28, 2026

Iothic and Carahsoft Technology Corp. said they entered a partnership to make Iothic’s CORE (d)OISP platform available to the Public Sector through Carahsoft’s reseller channels and contract vehicles. The update matters because it defines a distribution pathway for a decentralized authentication approach described in the release.

The agreement positions Carahsoft as Iothic’s Public Sector distributor and names multiple procurement contracts through which CORE (d)OISP would be offered. The release also frames CORE as intended to support adoption of Zero Trust mandates by reducing dependence on stored credentials and certificate or key lifecycle management.

CORE is described as using ephemeral, machine-generated synchronization keys and trust properties of the network itself, rather than long-lived credentials such as certificates, keys, or shared secrets. The company said the decentralized model strengthens authentication, improves data integrity, and simplifies secure access to digital objects.

Carahsoft said CORE is available through its SEWP V Contracts NNG15SC03B and NNG15SC27B, ITES-SW2 Contract W52P1J-20-D-0042, NASPO ValuePoint Master Agreement #AR2472, TIPS Contract #220105, and OMNIA Partners Contract #R240303. William Sullivan, CEO of Iothic, said, “In an age of AI-speed warfare, we can no longer afford to 'manage' risk; We must mathematically eliminate it—Iothic Core is the first step toward a truly unhackable nation,” said William Sullivan, CEO of Iothic. “Partnering with Carahsoft is a significant milestone in expanding the reach of our security platform to the Public Sector, and we are pleased to be part of a collaboration that provides streamlined access to our solution that will further protect Government agencies’ mission-critical assets.”

Michael Shrader, Vice President of Intelligence and Innovative Solutions at Carahsoft, said, “We are pleased to partner with Iothic to bring its innovative decentralized authentication platform to the Public Sector,” said Michael Shrader, Vice President of Intelligence and Innovative Solutions at Carahsoft. “As Government agencies continue to modernize their cybersecurity strategies and advance Zero Trust initiatives, they need solutions that reduce complexity while strengthening protection across increasingly distributed environments. By making Iothic’s CORE (dOISP) platform available through Carahsoft’s reseller partners and contract vehicles, we are helping agencies more easily adopt a modern approach to authentication that reduces credential-based risk and supports the secure operation of critical systems and infrastructure.”

CISA issues update on missing IPsec integrity for Verizon IMS SIP signaling

June 2, 2026

Overview VoLTE deployments on Verizon’s IMS network have historically lacked IPsec-based integrity protection for SIP signaling, contravening well-established requirements in 3GPP TS 33.203 and GSMA IR.92. As a result, SIP messages—including registration (REGISTER), call setup (INVITE), and messaging (MESSAGE)—were transmitted in plaintext without cryptographic guarantees of integrity or authenticity. Passive analysis of live traffic over multiple months confirmed the consistent absence of SIP Security Agreement headers and ESP traffic, indicating a systematic configuration decision rather than an isolated anomaly. In response to repeated follow-up inquiries, Verizon stated on [insert date] that integrity support is “currently available at their request” and will be extended to all UEs “starting later this year.” Separately, the researchers recently observed that Apple’s iOS 26.5 carrier bundle (released May 11, 2026) includes IMS IPsec-related configuration entries—an indication that device-side support may now be active or enabled in newer software. While this change is promising, its real-world impact remains uncertain: there is no evidence yet that Verizon has modified its network to enforce IPsec, that the configuration is being activated per session, or that integrity is functionally operational in production deployments. Absent explicit verification (e.g., captured ESP traffic or official confirmation), this may reflect preparatory software changes rather than an end-to-end security upgrade. The vulnerability remains active for the vast majority of Verizon VoLTE users during the unprotected period, and until network-level enforcement is observed and confirmed, the risk of on-path signaling manipulation endures. Description CVE-2026-10629 SIP signaling stack in Verizon IMS (unspecified version) implements SIP signaling without IPsec integrity protection (missing Security-Client/Security-Server headers and ESP traffic), which allows an on-path attacker to compromise confidentiality, integrity, and authenticity of VoLTE signaling via passive monitoring and active manipulation of unsecured SIP messages over the radio and core network. According to 3GPP TS 33.203 and GSMA IR.92, SIP signaling between the UE and P-CSCF in IMS networks must be protected using IPsec ESP with mandatory integrity following IMS AKA authentication. This protection is negotiated via SIP Security Agreement headers (Security-Client, Security-Server, Security-Verify) during registration and results in integrity-protected ESP traffic for all subsequent signaling messages. However, observations conducted over several weeks on Verizon’s network showed no such headers in use. The REGISTER exchange lacked any security negotiation, and post-registration SIP traffic—including INVITE, MESSAGE, BYE, and UPDATE—traversed the network in plaintext over standard UDP/TCP, with no ESP encapsulation. This pattern was consistent across device models and network conditions, indicating a systemic configuration decision rather than a transient issue. The absence of integrity checking means any modification to SIP messages—including redirection of emergency calls or injection of fake message payloads—would go undetected by both the UE and the IMS core. No technical justification for this deviation from globally adopted security practices has been provided by Verizon, and prior engagement failed to elicit a substantive response beyond the recent, non-binding commitment to future deployment. Impact The lack of IPsec integrity protection enables on-path attackers—including those controlling femtocells, compromised base stations, or IMS intermediaries—to intercept, modify, replay, or inject SIP messages without detection. These capabilities permit call hijacking, spoofing of SMS-over-IMS, denial-of-service through forged BYE or CANCEL, and manipulation of emergency call routing—without requiring compromise of the UE, SIM, or backend infrastructure. Because SIP signaling lacks cryptographic integrity, all such modifications go unnoticed by both the UE and the IMS core, undermining core security assumptions of VoLTE. While the recently observed iOS 26.5 configuration change may signal progress toward a more secure implementation, its operational impact is yet to be demonstrated; until then, the risk remains real and unmitigated for users on unprotected deployments. Solution Until the vulnerability is fully mitigated by Verizon, users and enterprises should continue to assume VoLTE signaling is untrusted for high-assurance operations.
